Nonsense. It would be one thing if you weren't practically a newbie pretending to be an expert. As you now know, the users having the problem had already done what you belittled them for not doing. Your "advice" did not work.I could swear that all these ppl complaining about mavericks installed it on top of a year old 10.8 or older OS. How many times must we say do a clean install? Format and do a clean install and come back and tell me if it's buggy!
Since upgrading to Mavericks, I have noticed one thing that I am sure many find annoying. The OS takes much longer to startup. Icons are slow to display even when opening a new Finder window. Everything is smooth and all. It is just slow. I have not noticed a similar slowness in productivity applications--just in the Finder. My hypothesis is that Apple made some changes in anticipation of vastly faster hardware. For those of us using older computers, the changes come at a price.
